So I actually joined Walmart+ with the $1 today, $75 later offer.
Looking around my account, I thought maybe I could cancel Walmart+ and then rejoin, with a paid membership. But it said I would have Walmart+ for another 29 days.
Poking in the “Your Walmart+ benefits” section where it says “Give theses benefits a try” there was a curious benefit.
"Early Access to Pokémon Week"
It said “Paid members shop Pokémon merch 3 hours early, starting at 10am ET each day!” And there was a button that said “Switch to paid”.
I closed the browser, went to the MyPoints portal and clicked through the “Join Walmart+ for Free Delivery on $35+ And Earn Up To 17,500 Points!” In my Walmart tab, I clicked on the “Switch to paid” button. I was offered Walmart+ for $98/year and my trial would end immediately. I agreed to the terms and clicked on “Start paid membership”.
What a roundabout way for me to get to paid Walmart+ membership. Hopefully it tracks on MyPoints!
